ALKALI METAL-CHALCOGEN BATTERY HAVING LOW SELF-DISCHARGE AND HIGH CYCLE LIFE AND PERFORMANCE

摘要

An alkali-chalcogen battery that includes a cathode that includes at least one of at least one chalcogen and at least one alkali-chalcogen compound, and an anode. At least one of an alkali metal-containing liquid electrolyte, gel electrolyte and solid electrolyte is disposed between the anode and the cathode. Also, a cation-selective separator is disposed at least in regions between the anode and the cathode, the separator being permeable for alkali metal ions and impermeable for polychalcogenide ions (Zn2− with n≧2, Z representing the chalcogen), and the separator having a maximum layer thickness of 30 μm.
